This is certainly an interesting treat. IBF is Steve Cammack(Dieter Müh) & Tim Bayes(Schuster)
This was a very short lived project, only active between 85-87. Most of the material usually hard to come by, so many thanks to Mr.Cammack for this donation to ATSLA. But if you are so inclined, you can still grab a vinyl release of IBF from Harbinger Sound(if you can find copies)

Note: Most of these are unindexed, so if you have had this previously then maybe you can fill in the proper list for us.
